It is threaded 1/2x28 with an A2 style flash hider that has not been pinned and welded meaning this must be attached to a pistol lower receiver. High pressure tested and magnetic particle inspected ensure this barrel is accurate and reliable. This Aero Precision AR-15 barreled upper is a great choice for finishing an AR build.
